A cumulonimbus capillatus is a mature and powerful cumulonimbus cloud and can produce multiple
severe weather. •
Lightning: this is a strong
thunderstorm cloud and it is capable of producing bursts of cloud to ground and cloud to cloud lightning. •
Hail: hailstones may fall from this cloud if it is in a highly unstable environment (which favors a more vigorous storm
updraft). • Heavy
rain: the cloud may drop several inches of rain in a short amount of time. This can cause
flash flooding. • Strong
wind: gale-force winds from a
downburst may occur under this cloud. • Weak to strong
tornados can occur. == External links ==
